A selection of 4x1x6 lego-compatible wall plates. Born of a need to make WH40K terrain, that was more intuitive than the Games Workshop kits.
Must be printed vertically. The studs will not be circles otherwise.
I took Chris Finke's lego file (thing:615256) and made a new function called wall_1. Wall_1 included a top 1x4x1/3 brick, and a flat 1x4x1/2 brick (to account for sagging on the unsupported flat bottom). The middle was then filled solid (because for a height of 6 bricks, I was sure that the inside tubes would break or something.
I then used surface(), to extrude reliefs on the walls, using various images from the Internet (hence non-commercial license).
